did you see the sunday nights redskins-giants game? here is what is happening -- what happened. they were initially told by officials they made a first down. by a long -- after a long passing play that was incomplete, they learned they were short on the previous play, which means that the first down had been a third down. then on what became a fourth down, the redskins turned the ball over and it sealed the giants win. i know, it's complicated. one way this could have been avoided was to more accurately measure the field in the first place. the technology is already on the tv, right? pimm fox spoke with the ceo of the company that is making this thing and reality. >> we have patented technology that is designed to project a laser on the field so that it can be seen by everyone in the stands, the players, and the coaches. and eventually, we hope to be able to replace the chains so that automatically, the referees can see if it is a first down line and it might have avoided the problem it had last night. >> why didn't they do this, or is it a long process they have to go through?
